4 colligative properties

Colligative Properties - Certain properties of solutions depend only on the number of particles of the solute (molecule or ions) present in definite volume of the solution and do not depend on the nature of solute. Such properties are called colligativeh..

Colloidal particles have high average molecular masses. Therefore the mole fraction of the dispersed phase is very low. Hence, in colloidal solutions the relative lowering of vapor pressure, elevation in boiling point, depression in freezing point and osmotic pressure is very low. However, osmotic..

The excess pressure that must be applied to the solution/conc.solution to prevent osmosis. fig 3.11 - Principle of measuring osmotic pressure fig 3.12 If two solutions of identical composition but different concentration are separated by a semi permeable membrane (one that permits only the solvent ..

Freezing point of a substance is defined as the temperature at which the vapor pressure of the solid form is in equilibrium with liquid form of the substance. In other words, solid and liquid forms of the substance has same vapor pressure. fig 3.10 The curves AB, BC, and A'B' are the vapor pressure..

1) It is soluble in hot water. 2) It is in the form of purple crystals. 3) On heating KMnO 4 decomposes to potassium manganate and oxygen...

1) Ammonium chloride is a colourless crystalline solid. 2) It is fairly soluble in water. Solubility of ammonium chloride in water is 41.4 g at 30 o C. 3) When it is dissolved in water, it absorbs heat and causes cooling. 4) When heated it undergoes dissociation to give ammonia..

CuSO 4 is easily soluble in water as it is in the form of crystals. When CuSO 4 is heated it decomposes into copper oxide and SO 3 . ..

Some physical characteristics of carbon dioxide are given below M.P B.P. Density (273K) CO bond length D Hf 216.4 K 194.5 K 1.977 g/L 116.3pm -393.5kJ/mol(5.2 atm) (Sublimes) CO 2 is a colorless gas with a faint pungent smell. It is about 1.5 ..
